build: fix build breakage due to bad merge
34bb443ee74df3780d86044dbf6492eb798c5807 broke the build but in a subtle way.
The patch on the ML was actually based on the 1.1.1 stable branch
(accidentally). When I merged it from the ML, the fuzzing got resolved in a
such a way that the newly introduced Makefile dependency on GENERATED_HEADERS
got lost (that was not in 1.1.1).
The dist bits also got duplicated (but this is just cosmetic).

Add vgabios build rules to roms/Makefile
This patch adds some glue to roms/Makefile to build vgabios binaries for
qemu. It covers both the lgpl'ed vgabios implementation used by qemu
traditionally and the new seabios implementation.
The purpose of this patch is to (a) document the vgabios build process
and (b) simplify seavgabios testing for those who want to play with it.
Move down the expire time calculation down in the frame timer, to the
point where the timer is actually reloaded. This way we'll notice any
async_stepdown changes (especially resetting to 0 due to usb activity).
With the async schedule being kicked from other places than the frame
timer (commit 0f588df8b3688b00e77aabaa32e26ece5f19bd39) it may happen
that we call ehci_commit_interrupt() more than once per frame.
Move the call from the async schedule handler to the frame timer to
restore old irq behavior, which is more correct. Fixes regressions
with some linux kernel versions.

usb: add usb attached scsi emulation
$subject says all. First cut.
It's a pure UAS (usb attached scsi) emulation, without BOT (bulk-only
transport) compatibility. If your guest can't handle it use usb-storage
instead.
The emulation works like any other scsi hba emulation (eps, lsi, virtio,
megasas, ...). It provides just the HBA where you can attach scsi
devices as you like using '-device'. A single scsi target with up to
256 luns is supported.
For now only usb 2.0 transport is supported. This will change in the
future though as I plan to use this as playground when codeing up &
testing usb 3.0 transport and streams support in the qemu usb core and
the xhci emulation.
No migration support yet. I'm planning to add usb 3.0 support first as
this probably requires saving additional state.
Special thanks go to Paolo for bringing the qemu scsi emulation into
shape, so this can be added nicely without having to touch a single line
of scsi code.

scsi: add free_request callback
Most device models have a simple lifecycle for the hba_private field
and they can free it when a request is completed or cancelled.
However, in some cases it may be simpler to tie the lifetime
of hba_private to that of the included SCSIRequest. This patch
adds a free_request callback to SCSIBusInfo that lets an HBA
device model do exactly that.
Normally, device models use req->hba_private == NULL to flag requests
that have been completed already. Device models that use free_request
will still need to track this using a flag. This is the reason why
"converting" existing HBAs to use free_request adds complexity and
makes little sense. It is simply an additional convenience that is
provided by the SCSI layer. USB-attached storage will be the first

fdc: rewrite seek and DSKCHG bit handling
This bit is cleared on every successful seek to a different track (cylinder).
The seek is also called on revalidate or on read/write/format commands which
also clear the DSKCHG bit.

block: introduce bdrv_swap, implement bdrv_append on top of it
The new function can be made a bit nicer than bdrv_append. It swaps the
whole contents, and then swaps back (using the usual t=a;a=b;b=t idiom)
the fields that need to stay on top. Thus, it does not need explicit
bdrv_detach_dev, bdrv_iostatus_disable, etc.

block: copy over job and dirty bitmap fields in bdrv_append
While these should not be in use at the time a transaction is started,
a command in the prepare phase of a transaction might have added them,
so they need to be brought over.

blkdebug: store list of active rules
This prepares for the next patch, where some active rules may actually
not trigger depending on input to readv/writev. Store the active rules
in a SIMPLEQ (so that it can be emptied easily with QSIMPLEQ_INIT), and
fetch the errno/once/immediately arguments from there.

sheepdog: traverse pending_list from the first for each time
The pending list can be modified in other coroutine context
sd_co_rw_vector, so we need to traverse the list from the first again
after we send the pending request.
